The compressing of lubricant into the groove or grooves of the bullet being accomplished by moving the entire mechanism against a plurality of plungers or pistons in contact with a stationary member.

Another object is to supply such mechanism with novel means for regulating or controlling the discharge capacity of the ducts or passageways connecting the sources with the die means so that a certain amount of lubricant is conveyed to the die means by the feeding means during a greasing operation.

Another object of my invention is t provide new and improved means for spacing the adjacent ends of. the dies which function to form an annular lubricant chamber in order to regulate or control the size of such chamber.

Other objects of my invention are the provision of means for indicating the amount of lubricant contained within the reservoirs; the provision of means to oppose the movement of the plurality of plungers or pistons slidably fitting within the lubricant reservoirs in order to prevent the discharge of grease before the bullet is properly positioned withinthe die means; the provision of a bullet sizingand lubricating device which is reliable and fast in operation, simple in its construction, and whereby the bullets will be more accurately sized and more evenly lubricated than with the known devices of this general character.

The foregoing and other objects, features, and advantages will be clear from the following description in connection with the accompanying drawings, in which:

Fig. 7 is a sectional view taken on the line |l of Fig. 6.

Referring first to the embodiment of theinvention illustrated in Figs. 1 to 5, inclusive, 8 designates a horizontally disposed base or supporting frame comprising angle iron spaced side bars 9 rigidly connected together at one end by an inclined cross bar' It! provided with apertures H for a purpose hereinafter described. The opposite ends of the side bars are secured together by a stationary shaft [2 on which i pivotally mounted a framel3 comprising side bars l4 and 15, rigidly connected by cross bars l6 and H.

The frame l3 is pivotally connected at its upper end to a body l8 having trunnions l9 and 20 journalled in apertures 2| in the side bars of the frame.

The body is provided midway between its length with a threaded aperture or bore 22 which extends through the body so as to receive at its lower end a hollow threaded plug 23 having an internal shoulder 24 on which a tubular die or bullet grasping member 25 rests. The upper end of the aperture 22 is closed by a tubular threaded plug 26 having an internal shoulder 21 on which rests a tubular die or bullet grasping member 28. A third tubular die 29 is arranged in he bore of the part 26 and rests on the die 28, and both dies 28 and 29 are secured in the plug 26 by means of a threaded tubular entrance member 36 which is in threaded engagement with the upper end portion of the plug 26.

As shown in Fig. 2a, each of the dies 25, 2B and 23 is preferably provided with a bore 3| tapered away from the mouth 32 of the bore so as to compress a bullet 33 as the latter is driven successively through the dies by any suitable means, such as a punch 34 having a ram 35 at one end thereof which forms an abutment 36 adapted to contact with the entrance member 30 to limit the extent to which the punch can be driven into the bore formed by the dies. It will be observed from Figs. 2 and 5 that as the parts 23 and 26 have threaded engagement with the body I8, they can be moved toward or away from one another to vary the distance between the dies 25 and 28 to facilitate the introduction of lubricant or grease into the groove or grooves 31 of a bullet while the latter is in a stationary position and grasped by the dies 25 and 28. In this connection, it will be noted that when the punch is in its innermost position (Fig. 5), the groove or grooves of the bullet will be properly positioned to receive lubricant.

Any suitable means may be provided to lock the parts 23 and 26 in adjusted position. For example, as shown in Fig. 3, a screw 38 may have threaded engagementwith the body [8 to press upon a leather disc 39, or the like and press the latter against the threaded portion of the plug 23 or 26.

The body I8 is provided at diametrically opposite sides of the threaded aperture 22 with lubricant ports 4|] and 4| through which lubricant may be simultaneously forced from opposite directions into the space between the inner ends of the plugs 23 and 26 to enter the groove or grooves of the bullet while the latter extends into the dies 25 and 28.

To supply the lubricant, the body I8 is provided with a pair of threaded apertures or bores 42 and 43 arranged in parallel relation to the aperture 22 and in close proximity thereto. Each aperture 42, 43 is provided with an adjustable threaded plug 44 having a conical extremity 45 to cooperate with the fiared mouth 46 of a lubricant reservoir or cylinder 41. Each cylinder has external threads at its upper end to screw into the threaded aperture 42 or 43 and it is obvious that the tapered ends 45 of theplugs function as valves to regulate the amount of lubricant which may travel from the interior of either cylinder toward lubricant port 40, 4| with which it communicates.

Either plug 44 may be locked in adjusted position by means such as the parts 38, 39 (Fig. 3).

Lubricant may be introduced into the body and into the cylinder if desired through a port 48 arranged at one end of the body and closed by a threaded plug 49.

Each cylinder is provided with a piston or plunger 50 having a tapered extremity 5| adapted to extend into one of the apertures I; of the sta-;

tionary cross bar In so that the latter. actaas' a stop or abutment for the plungers. while the cylinders move relatively thereto.

For indicating purposes, each lunger is provided at 52 with three indicating lines, at 53 with two indicating lines, and at 54 with a single indicating. line.

of the cylinder, the latter will contain a full charge of lubricant; When the lines 53 register" withithe endof the cylinder, thecylinder will .be

half full andwhen the line 54 coincides with :the

endof the cylinder, the latter will be empty.

Each cylinder is provided with abrake (Fig. 4) to normally-resist movement of the cylinder relatively::to:the piston; The brake may consist of .a band fifi surrounding .the cylinder and anchored thereto by means of an. impingement screw 51. An auxiliary cylinder 5&extends from the band and has a bore 59 in which a detent or axially movable lug. 6E1 slides. The inner end of the latter. extends through an aperture El in the cyl inder and. bears against the piston 50. A spring 82 is employedlto yieldingly force .the pin toward the, piston and the compression of the spring is adjusted bymeansof.a threaded plug 63.

Byvirtue of the indicating feature 5255, the reservoirs may be .filledto accommodate thevery hard viscous lubricants which are difiicult to force into the die means. In my above-mentioned patent, Ihave pointed out the advantage of having the source of lubricant in closeproximity'to the bullet; and by reducing the amount of lubricant in the reservoirs, the driving pistons 58 will be brought in close proximitytothe bullet thereby reducing the resistance between the driving force and the die means. Of course, the duct or lubricant passageway, is fully opened by moving the control plug or valve 44 upwardly and away from the tapered mouth of the grease reservoir. From the foregoing, it is to be understood that the operator would fill the reservoirs to capacity when using the softer typesof grease and reduce the amount of lubricant inthe reservoirs when usingmore viscous'types. By properly manipulating the valves 44, a variety of lubricants may be evenlyand uniformly applied to bullets.

In order to'balance the driving force of the pistons against the easy flowing soft lubricants, the communicating passages between the cylinders and the-bullet may be restricted by moving the conical ends of the valves 44 intoclose proximity to the :tapered surfaces of the mouths of the reservoirs. However, va condition will occur which will beexplained'later, whereby the driving forces of the pistons mustbe further reduced to prevent Reference to my prior Patent 2,403,032, will.

clearly explain how an annular lubricant chamber is formed between the adjacent ends of dies ZS-and 28 as well as the advantages of using a plurality of dies.

In operation, after theadjustable members of the'apparatus have been placed in readiness for operation, a bullet is introduced into the mouth ofthe entrance member 3i nose first; then, the punch .24 is employed to force the previously As such. lines .cooperate with the lower endt'fi'ofthe cylinder, it willhe understood that when the linesfizregister with the lower end I: inserted bullet into :ztherbora of the. die-means; I211SllChi:OpQratiOH;thEiJram .65 isistruckzwith: a2, mallet or hammer: whilez thepentrance. member? 30 guides sithe punch:- while 't;;,drives the bullet ahead"intoithezboreiof thedrextZQ.

Consequently; the lubricant contained within :the reservoir is put under a-series of pressures, and grease is pressed into the groove-or+grooves-of a :bullet:

that is positioned between thead-j acent ends of. the dies 25- and zki- Like in'my; prior-patent, lubricant will beapplied'to the bullet grooves or groove in spurts; Furthermore,- during the greasing operation, lubricant is forceddirectlyonoppm site sides oithe bullet simultaneously. As a result', no lubricant is forced ar-oundthebulletandi then pressed back by back pressure-onthe oppo site side thereof. There is nocompacting of grease on one side of the Joullet'sincebothbf its sides receive grease at the same time.

As:previously. indicated, the-problem involved in satisfactory lubrication :ofbullets, is the direct application of'grease to all parts of thesbullet grooves circumferentia-lly, and-for this purpose,- I provide means to: force grease into the. die means in two opposite directionssimultaneously. Preferably; and as .disclosedherein, the lubri can-t is forced from separate sources. ItLm-ust. be remembered that lubricant forced froma single source will eventually end by backing and compacting within the die' means; regardless of how many: pistons have boosted the: grease during its journey from the source of: supply to the. die'means. In: accordance with theinvention, the grease. :iszpreierabiy forced into: the-diemeans- (A) from separate sources .(B) from. opposite directions. (0) simultaneously (D) at the: time a bullet .is-properly positioned. within the die means.

From the foregoing, it will be understoodthat.

in thergeneral operation of:-the device, a bullet is placed in the mouth of the apparatus, and. a suitable punch attached. to an operatingram. inserted ;a few blows with .a mallet .or hammer;

onthe ram, and the'rresultqisaccomplished; The;

operating punch and ram are then removed, another bullet is placed in the mouth of the apparatus and the operation repeated. Bullets are thus forced through the dies one after another and each one is properly sized and lubricated. The greasing operation, as previously explained, is entirely automatic and the bullets are lubricated when accurately positioned within the bore of the die means by frictional means that allow discharge of lubricant into the die means only when desired. The ejection of the bullets from the die 25 is also automatic.

Instead of employing a pivoted or freely movable frame to support the body or housing l8, it is obvious that such body might be fixed and supported in a stationary manner. Of course, this change will eliminate the automatic greasing operation feature; but, the novel feature of direct lubrication effect in opposite directions, could be retained. Such an embodiment could have a plurality of lubricant sources, and a plurality of plungers or pistons adapted to be struck by a mallet or hammer when it is desired to force lubricant into the die means. If such an embodiment is desired, a modification of the invention may be employed in connection with a cartridge reloader of the type shown in Patent 1,933,940, dated November '7, 1933. The embodiment illustrated in Figs. 6 and 7 will serve to disclose the principles of construction and operation in keeping with this form of the invention. The main body 20a, is altered so that the axes of the reservoirs 41a and pistons 50a are perpendicular to the axis of the central bore 22a which accommodates the die means; that is, the axes of the bores 42a, 43a and. 22a would not all lie in the same plane. The altered main housing with its appurtenances, may be attached to the upper arm 64 of the cartridge reloader 65 in any suitable way with the entrance member 30a of my device uppermost (Fig. 6). In such a structure, the cartridge reloader merely functions as a support for my device. Bullets are passed through the device so supported, by a punch 34a driven by a mallet or the like. In this form of the invention, the plungers 50a (Fig. '7) are rigidly connected by a bar or yoke 6'6 having a ram 61 attached to the medial portion thereof.

In the operation of this embodiment, bullets are passed downwardly by means of the punch to drive the bullet to the lubricating position, as illustrated in Figs. 2 and 5. Then the ram. 61 is is struck with the mallet and this will cause the grease to flow in spurts from opposite directions directly into the groove or grooves of the bullet.

Attention is directed to the yoke 66 which serves to move both plungers or pistons simultaneously when it is desired to force lubricant through the passageways controlled by the cones 45a. The modified form of the invention is simpler nd less expensive to manufacture than the preferred form; and, the greasing is not automatic; but, the difliculty which is encountered by the compacting of grease within the die means is avoided. The ejection of bullets in both forms of the invention is entirely automatic as the bullets introduced into the mouth of the die means function to displace the processed bullets within the apparatus which fall through the exit and of the die means.

While I have disclosed, by way of example, the preferred forms of the invention, changes in construction and arrangement of parts thereof may be resorted to without departing from the field and scope of the same, and I intend to include in 8 this specification all such variations in the method and apparatus as fall within the scope of the appended claims.
